True because I wanna be a chemist so i watch these

Must be a amazing feeling seeing your students grow up and make discoveries of their own.

My dad is a thalidomide baby. We are from Australia, he is 62 years old and his mum, my nan took thalidomide for its antiemetic properties and dad was born with two heavily disfigured arms. One of dads arms is extremely small and mostly useless, and the other is about 1/3 the length of a normal arm, but just completely different. He doesn't have a normal hand, and has very limited dexterity. His longer arm is curved, and when he was born is was bent backwards. He went under years of surgery and rehabilitation as a kid. They corrected his arm, so it is forward facing and useful. As he is getting older now, and has very short arms he has to do a lot of bending, and that is catching up to him and he is getting more aches and pains in his back and other parts. His arm is always and has always been painful. Dads whole life has hadn't met any other thalidomide victims until the past 5 or so years they have all been put in contact due to an ongoing lawsuit. There are ~30 thalidomide survivors in Australia, and they meet up every couple of years. Dad has become good friends with a handful, and acts as a bit of a mental health ambassador for them, as mental health has been a big issue with some, due to their physical issues.

It's a German invention and was used in my country until the 1980s 😢 It's one of the isomers. So i still see disfigured people a lot.

Thalidomide is actually quite useful, not just for treating leprosy but for several cancers. It's on the WHO List of Essential Medicines. It just can't be given to pregnant women anymore due to the huge risk of severe birth defects. It also is no longer given for insomnia or anxiety like it used to, due to some other small but significant side effects.

This was the FDA’s claim to fame here in the States. The FDA had recently been commissioned and they hadn’t approved Thalidomide by the time its effects were coming to light

@xyzpdq1122

Ай бұрын

The FDA repeatedly rejected thalidomide because the company’s tests were inconclusive or shoddily prepared. The head of the FDA at that time insisted on better, more independent testing. The thalidomide tragedy was also the impetus for testing new drugs on pregnant women (or, more likely, primates). Before then, it was thought that drugs couldn’t pass the placental barrier.

It’s so cool seeing someone so passionate from a young age transform into a person that does it. Way to go Edoardo!

This channel is one of the best things ever.

When my mother was pregnant with me, in 1960, she was offered Thalidomide for stomachpains. She refused, without knowing what it did, and i was lucky. Many others whos mothers got Thalidomide was not.

I discovered this channel back in 2012 when I was 12 and it inspired me to pursue chemistry more since it was the most acessable science to me in my school at the time. I ended up taking AP Chemistry and it led me to taking physics in highschool since I didn't want to pursue the Biology track. I took physics and ended up pursuing Electrical Engineering in college and it let to where I am as an Engineer in the US Space Force. Sufice it to say, this scratched the itch of curiosity and made chemistry accessible to me at that young age and I want to say thank you for inspiring me and my cohort of my generation to being the next generation of scientists, and engineers.

This video warms my heart! I'm nearing the end of my PhD studies and I owe a lot to Prof Poliakoff and PeriodicVideos. You really helped me discover my passion for chemistry and research!

I always feel a great affinity for kids who have an interest in a specific field very early and then they end up shooting straight for it like the way Edoardo did with chemistry. I did the same thing with computers, as soon as I touched one as a kid I knew I was instantly hooked and would spend my life working with/on them. If any kid expresses interest, I'll do anything I can to help them. Never write off a kids interests as "a phase", especially if they're around that 10-12 age range. Read any biography and I guarantee you that no matter who it is you're reading about, something set the path of their life around that age. People don't figure out what they want to do when its time to go to college in most cases, they either know it all along or they never quite figure it out.

Most people think Thalidomide was not tested for adverse effects but that is incorrect. It's adverse effects on the embryo only occur over a 16 day period in the growth of the embryo and testing missed that period.

I'm a pharmacist, very interesting stuff! We actually have cancer patients in my hospital that use thalidomide. We have a REMS program (Risk Evaluation and Mitigation Strategies) for it, so it can only be used safely- that's the hope for the program anyway, and it seems to work just fine. it's interesting to see "in the wile" so to speak, a case study of one of my patients presenting with thalidomide for cancer, then I go look it up and go "wow, we really still use this?" and then I see this video! great stuff

I've heard about this REMS, but couldn't find much of a thing here in Aus except the TGA which wasn't much use, I wanted to give a detailed report on my devastating experience with some meds I was put on that I couldn't find any other cases of except a few that contacted me privately from other counties that had the same reactions after seeing my public posts about it. I found it very frustrating that the manufacture of the drug didn't have any way to report or contact. So I feel like myself and others are living a similar situation that people that were affected by thalidomide had to endure with little to no acknowledgment of the problem all those decades ago. I wonder if there is a global program where you can report adverse events?

I like how old school this video feels. 2 or 3 different threads being discussed at the same time.

I have to be sincere here. This channel made me took a yearly chemistry 101 class before applying to paramedic school. I didn't get a good chemistry education in HS (and I blame myself for this as well, because the teacher was very good). I got average/mediocre scores in the class, but I learned enough to pass biochemistry classes later on with flying colors. I thank the whole team of Periodic Videos for teaching me to be sincere with myself about my lack of knowledge in chemistry and do something to remedy that situation.

Full circle, how awesome is this!

FWIW, these channels don't just inspire STEM students. I got my degree in engineering, but I'm also a professional author on the side, and Periodic Videos, Numberphile, Objectivity, etc. have contributed to several of my stories.

@@tommunyon2874 What often happens is during drug discovery/development period, a purpose for the drug is proposed or discovered, but often it doesn't work as expected or there is already existing ones on the market that work better, but during trials and further research the unexpected effects or side effects can sometimes be very useful for something that is marketable, so research direction changes and the drug may tick the boxes to be approved as something else. There is 1000s of drugs and compounds being developed and discovered all the time and the ones that make it to market occasionally were meant for something else but changed direction when they find it better suited for a unrelated treatment. Kind of like how Viagra was originally developed for a heart condition but the side effect of ED improvement and it's lack of effect on the heart condition made it end up as what it is today. And Viagra has potential use outside of ED treatment too, more recently found to have neurogenesis and psychiatric properties and among other stuff.

"...you were my stars..." - let's hope that there will always be those stars around us.

Brady, I used to use a pestle and mortar routinely, albeit on a much smaller scale. When I was a student, when we wanted to take an infrared spectrum of a substance we had synthsised, we needed to suspend it in a minimal volume of an oil called nujol. To do this, we'd mix it in a little mortar with a little pestle. The resulting paste was known as a "nujol mull". You would then sandwich this between two chunks of sodium chloride (which is transparent to infrared) to put it in the spectrometer and take your spectrum.

9:44 Well said Professor! Much love from Holland ❤

I was originally interested in chemistry which stemmed from an amazing high school chemistry teacher I had. I went to undergrad and started on my chemistry journey, took about 2 years of organic chemistry classes but during those years it was required to take physics/math courses as well. Turns out I was far more interested in physics than chemistry, learning how everything around me works and can be described and predicted mathematically. Chem seems to work in probabilities and often seems to have exceptions to the rules I was taught about how chemicals should react with eachother given their electrophilic etc nature for example. So I pivoted to physics and math, which I thoroughly enjoy, and now I’m applying that knowledge as an engineer after grad school. Long story short, science teachers inspire students more than they realize, even if they don’t seem super interested in the subject at the time or if they end up in a different STEM field

Gotta wonder how many kids this channel inspired to continue their education in some chemistry field. Crazy how much influence a few people and some good production can have.

Thanks!

I've always wondered what they do with all the left over stuff at the end. You've got the leftovers from the reaction, cleaning solvents etc. in liquid form. Certainly can't put it down the drain, must be treated in some way. Wouldn't mind a video showing how that's cleaned up.
